The events building up to the eruption were quite typical and similar to the previous paroxysms: at first, the until-then intermittent and mild strombolian activity from the New SE crater gradually picked up, starting from around 10 pm local time. At the same time, volcanic tremor started to show a steep increase, sign of magma moving upwards inside the volcano's conduits.
The activity began to turn into sustained lava fountains from around midnight, and continued to increase in intensity. Around 00:30, the activity reached its peak phase with very tall lava fountains surpassing 1000 m height! An impressive eruption column of ash and steam rose to probably more than 10 km altitude and spread into an impressive, near-circular umbrella cloud towering over eastern Sicily.
At around 1:05 am, activity quickly ceased, with a phase of reactivation during approx. 4.40 and 6 am, when a series of strong explosions occurred at the SE crater complex.
Similarly to the previous events, lava flows were erupted to the SW and the east of the New SE crater into Valle del Bove, reaching similar lengths as before.
